Magento ODBC Driver

The Magento ODBC Driver is a powerful tool that allows you to connect with live Magento data, directly from any applications that support ODBC connectivity.

Access Magento like you would a database - read, write, and update Customers, Inventory, Products, Orders, etc. through a standard ODBC Driver interface.



Create data visualizations and use high-performance statistical functions to analyze Magento data in Microsoft R Open.

Access Magento data with pure R script and standard SQL. You can use the CData ODBC Driver for Magento and the RODBC package to work with remote Magento data in R. By using the CData Driver, you are leveraging a driver written for industry-proven standards to access your data in the popular, open-source R language. This article shows how to use the driver to execute SQL queries to Magento data and visualize Magento data in R.

Install R

You can complement the driver's performance gains from multi-threading and managed code by running the multithreaded Microsoft R Open or by running R linked with the BLAS/LAPACK libraries. This article uses Microsoft R Open (MRO).

Connect to Magento as an ODBC Data Source

Information for connecting to Magento follows, along with different instructions for configuring a DSN in Windows and Linux environments.

Magento uses the OAuth 1 authentication standard. To connect to the Magento REST API, you will need to obtain values for the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties by registering an app with your Magento system. See the "Getting Started" section in the help documentation for a guide to obtaining the OAuth values and connecting.

You will also need to provide the URL to your Magento system. The URL depends on whether you are using the Magento REST API as a customer or administrator.

  • Customer: To use Magento as a customer, make sure you have created a customer account in the Magento homepage. To do so, click Account -> Register. You can then set the URL connection property to the endpoint of your Magento system.

  • Administrator: To access Magento as an administrator, set CustomAdminPath instead. This value can be obtained in the Advanced settings in the Admin menu, which can be accessed by selecting System -> Configuration -> Advanced -> Admin -> Admin Base URL.

    If the Use Custom Admin Path setting on this page is set to YES, the value is inside the Custom Admin Path text box; otherwise, set the CustomAdminPath connection property to the default value, which is "admin".

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Linux

If you are installing the CData ODBC Driver for Magento in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData Magento Source] Driver = CData ODBC Driver for Magento Description = My Description OAuthClientId = MyConsumerKey OAuthClientSecret = MyConsumerSecret CallbackURL = http://127.0.0.1:33333 Url = https://mymagentohost.com

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Load the RODBC Package

To use the driver, download the RODBC package. In RStudio, click Tools -> Install Packages and enter RODBC in the Packages box.

After installing the RODBC package, the following line loads the package:

library(RODBC)

Note: This article uses RODBC version 1.3-12. Using Microsoft R Open, you can test with the same version, using the checkpoint capabilities of Microsoft's MRAN repository. The checkpoint command enables you to install packages from a snapshot of the CRAN repository, hosted on the MRAN repository. The snapshot taken Jan. 1, 2016 contains version 1.3-12.

library(checkpoint) checkpoint("2016-01-01")

Connect to Magento Data as an ODBC Data Source

You can connect to a DSN in R with the following line:

conn <- odbcConnect("CData Magento Source")

Schema Discovery

The driver models Magento APIs as relational tables, views, and stored procedures. Use the following line to retrieve the list of tables:

sqlTables(conn)

Execute SQL Queries

Use the sqlQuery function to execute any SQL query supported by the Magento API.

products <- sqlQuery(conn, "SELECT Name, Price FROM Products", believeNRows=FALSE, rows_at_time=1)

You can view the results in a data viewer window with the following command:

View(products)

Plot Magento Data

You can now analyze Magento data with any of the data visualization packages available in the CRAN repository. You can create simple bar plots with the built-in bar plot function:

par(las=2,ps=10,mar=c(5,15,4,2)) barplot(products$Price, main="Magento Products", names.arg = products$Name, horiz=TRUE)
